The Signal Index
Methodology
How we build, score and maintain the HealthTech Signal rankings.
Top 100 HealthTech Startups
The Signal Score is a composite of five weighted signals. Our research desk gathers public funding data, regulatory filings, published evidence, hiring signals and brand visibility, then scores each company against the same rubric.
Total raised, quality of investors and recency of the last round.
Revenue trajectory, customer count, hiring and market pull.
Peer-reviewed evidence, FDA/CE clearances and live health-system deployments.
Founder track record, clinical depth on the bench and technical leadership.
Search presence, press coverage, founder and brand reach, and how often the company shows up where buyers look.

Top 100 Most Influential People in HealthTech
The Influence Score ranks clinicians, founders, investors, researchers, policy voices and journalists who shape how healthcare thinks about technology.
Audience size across LinkedIn, X, YouTube, podcasts and newsletters.
How much the audience actually reacts, comments, shares and subscribes.
Clinical, research, operating or investing track record behind the commentary.
Publishing cadence and how reliably they show up with original work.
Whether decision makers, policy and capital actually move on what they say.
Scores are compiled by our research desk from public platforms, peer-reviewed contributions, institutional leadership, and audience intelligence. The Top 100 Index is published biannually (March and September), complemented by monthly specialized vertical spotlights. Figures are estimates; if something looks wrong, .
The list is primarily algorithmically scored. Editorial judgment is reserved for tie-breaking and material updates that the model has not yet captured.
The startup leaderboard is frozen monthly; the Most Influential People index is frozen biannually (March and September). Archived editions remain unchanged.
Editions and archives
At the end of each publication cycle the live ranking is frozen as an archived edition: monthly for startups and biannually (March and September) for the Most Influential People index. Past editions remain available and unchanged. Profiles stay evergreen: a person or company that drops out of the current list keeps their page, badged with their last ranked edition.
